* UNITED STATES PATENT OF ICE;

FRED B. PARKS, OF GRAND RAPIDS, MICHIGAN.

PLIERS.

SPECIFICATION forming part of Letters Patent N 0. 653,920, dated July 17, 1900.

Application filed April 13, 1899. Serial No. 712,951. (No model.)

To all whom it may concern:

Be it known that I, FRED B. PARKS, a citi- 'tion to close the puncture without danger of increasing the size of the puncture and the pliers removed without danger of withdrawing the plug. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an elevation of my pliers. Fig. 2 is a plan of the same; and Fig. 3 is a side View of a portion of the pliers and a section of a tire, showing the manner of inserting the plug.

Similarletters refer to siinilarparts throughout the several views.

My pliers are of ordinary construction, except as to the jaws, which are made long, slim, and are curved or bent, as shown in Figs. 1 and 3, to form a graceful curve from the points to about one-third of the distance to the head. The point of the lower jaw A must project about three-sixteenths of an inch beyond the end of the upper jaw B, as shown at a, so that when entering the puncture to insert the plug D, as shown in Fig. 3, the head 61 of the plug will be grasped by the jaws of the pliers, and the under jaw will enter the aperture far enough ahead of the upper jaw to form a perfectly-rigid support bethe puncture, while the upper jaw standing back of the lower jaw will be embedded in the soft rubber of the head of the plug, so that its point cannot come in contact with the tire to tear the puncture larger. The outer surface of the jaws should be rounded, as indicated in the drawings, and both the outer and the inner surfaces should be polished as smooth as possible, so that they may be passed through the puncture with perfect ease and without danger of tearing it larger and so that they may be withdrawn without danger of drawing the plug out with them.

0 represents the head and handles of the pliers, which may be made in any of the ordinary forms of construction common to small 7 pliers.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is-

In bicycle-repair pliers, two members pivoted together at the point of crossing, a handle integral with, and projecting back from each member, a long slim tapering jaw inte gral with and projecting forward from each member both of said jaws formed upon a uniform curve in the same direction, from the member to the point of the jaw so that the concave surface of one fits over the convex surface of the other and the end of the inner jaw projecting beyond the end of the outer jaw, substantially as and for the purpose set forth.

Signed at Grand Rapids, Michigan, March 31, 1899.

FRED B. PARKS.
